Abstract

Located in the middle part of the Korean peninsula, Pyeong-chang and Yeong-wol (Gangwon-do) areas are limestone regions that are important biogeographically showing the peculiar flora. In order to manage efficiently endangered and rare plant species, we have investigated flora of these above regions from March to October, 2010. The result of the investigation showed a total of vascular plants of 1,145 taxa; 134 families, 503 genera, and 1,010 species, 11 subspecies, 110 varieties, 10 forms and four hybrids. Among taxa investigated, endangered species designated by the law called 'Protection Law for Endangered wild fauna and flora' were seven taxa, and 50 taxa were considered to be endemic to Korea. Based on the floristic degrees categorized by the specific distribution of plant species, 24 taxa revealed the floristic degree (FD) V, 30 for FD IV, and 60 for FD III, 45 for FD II and 79 taxa for FD I. The 82 taxa were identified to be naturalized. Of those species investigated in this survey, 53 taxa were identified as specific ones biogeographically as compared to flora of other terrestrial regions; 35 of calcicolous plants, 15 with distribution in the northern part of the Korean peninsula, three with coastal habitats.

한국의 중부에 위치한 평창, 영월 지역은 석회암 지역이며 생물지리학적으로 매우 중요한 지역이다. 2010년 3월부터 10월까지의 조사로 평창, 영월 지역의 식물상을 밝혀 석회암 지역 식물 연구의 기초자료로 활용하고자 한다. 이 지역의 식물상은 134과 503속 1,010종 11아종 110변종 10품종 4잡종의 1,145분류군으로 확인되었다. 환경부 법적보호인 멸종위기야생식물은 7분류군이며, 한국고유종은 50분류군이었다. 식물구계학적특정식물은 238분류군으로 5등급 24분류군, 4등급 30분류군, 3등급 60분류군, 2등급 45분류군, 1등급 79분류군으로 나타났다. 귀화식물은 82분류군이었으며, 본 조사지에서 다른 지역에 비해 특이하게 분포하는 식물은 53분류군이 확인되었다. 이 중 석회암 지역에서만 분포가 확인되는 식물은 35분류군이며, 격리되어 분포하는 북방계 식물은 15분류군, 해안성 식물은 3분류군이었다.
